FASTENING FOR SAl-'E OR VAULT PLATES.

SPECIFICATION formingpart of Letters Patent No. 713,881, dated November 18, 1902.

Application filed March 11, 1902. Serial No. 97,689. (No model.)

To all whom, it nfl/tty concer/'72,:

Be it known that I, HENRY DEMING H1B'- BARD, a citizen of the United States, residing in Plainfield, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Fastenings for Safe or Vault Plates, of which the following is a specification.

This invention relates to fastenings for safe or vault wall components or plates, the object of the invention being to provide a fastening which may be used with what is ordinarily understood to be unmachineable7 metal plates-that is, plates such, for instance,las manganese-steel plateswhich it is not practicable to drill or cut to form bolt-openings for the reception of bolts or other forms of fastening means necessary to be inserted through holes formed by such tools and by means of which fastening the wall components or plates will have their contiguous faces or edges brought together under high tension, thereby obtaining a high initial re-y sistance, which must be rst overcome before such plates can be separat-ed.

In the drawings accompanying and forming a part of this specification, Figure 1 is a view of a series of fastening devices connecting a pair of members or plates. Fig. 2 isa crosssectional View taken in line a a, Fig. 1. Fig. 3 is a top View of the fastenings shown in Fig. 1. Figs. 4 and 5 are perspective views of the fastening devices. Fig. 6 is a View of a different form of plates secured together by thisiinproved fastening means. Fig. 7 is a cross-sectional view showing the fasteningl also dierent parts of a safe or vault. In my 5o Patent No. 662,433, dated November 27, 1900,

I have shown plates connected by links shrunk onto projections of such plates. In the present instance in place of the links I use retaining members, which are likewise shrunk onto the projections of the plates; but these retaining members are in the form of tie-bolts, vand in the preferred form thereof, herein shown and described, they are in the form of I-shaped tie-bolts. Other shapes, 6o however, may be used.

This fastening comprises a plurality of proA jections 2 and 3, shown in the present instance as a pair thereof, rigid or integral with a pair of safe or vault members or plates 4 and 65 5 to be secured together. In the form shown each plate is provided with one or more projections 2 or 3, located at the inner side and adjacent to the edge thereof and in position to register with corresponding projections car- 7o ried by the other member or plate. The projections may be of any desired shape. For instance, instead ot forming them as separate and independent the plates may be provided with flanges 6, (see Fig. 6,) having transverse recesses 7 formed therein at intervals during the castingofthe platesfor the reception ofthe fastening devices. The projections 2 and 3 of the plates likewise forni intermediate recesses 3', similar to the recesses 7, except 8o that they are usually of somewhat greater depth, since the projections of each plate have no connecting-webs similar to the webs 9 of the lianges. To unite the projections together under sufficient tension to resist the opening of the joint, a retaining device is provided, which in the form shown comprises an angle member or tie-bolt 10, inserted between each two sets of projections 2 and 3 with parts thereof overlapping one or more 9o pairs of projections. In the main form shown this tie-bolt resembles an I-bolt, and when this form of bolt is inserted in position each transverse portion l2 overlaps a pair of projections of the same plate, each boltI thus holding in position two sets of projections. In the present instance the bolts are so located relatively to each other that each two of such bolts will completely surround a pair of projections; butthis could` be otherwise, `if desired. For instance, instead of forming the bolts I-shaped they could be E-shaped by omitting the parts shown at the left of thedotted lines, Fig. 5, the two remaining heads or transverse portions being of the same length or of a length to completely overlap the faces of the projections, or, if preferred for any reason, a portion of each head of the tie-bolt could be dispensed with, as indicated by dotted lines, Fig. 4, so that the bolt would be somewhat S-shaped, one head overlapping a projection of one set, whilethe other head overlaps a projection of another set. The preferable form, however, is the I-shaped bolt, since ythe strain on this form of bolt comes equally on all parts thereof and is transmitted to the perpendicular portion thereof from duplex parts at each side of the bolt, whileat the same time a pair of bolts of this form completely surrounds a pair of projections. In practice these tie-bolts having been first heated are inserted in the recesses between the projections and shrunk thereon, whereby the joints are formed under high pressure-that is `to say, the edge faces of the plates or members are drawn together with great force and under high tensionthereby obtaining high initial resistance, which, as will be readily seen, must be rst overcome before such members or plates can b e separated to eect an entrance into the joint. By this organization safes, vaults, and strong boxes may be made of highly resistant material and of a composite construction and which will be forall practicable purposes as strong as an integral structure, since the fastening devices, being shrunk on, become to a certain extent integral with the projections.

When the plates are large and heavy, it will b e seen thatl by providing a number of these Afast'eni-ngs located side by side at the desired intervals it will not be practicable to separate the plates, even by the use of high explosives, especially when such plates are formed of manganese steel or other unmachineable metal, since the edges of the plates being drawn together with great force and it beingI impracticable, as is well known, to drill into plates of this character sufficiently to permit the entrance of nitroglycerin, it follows that it is not practicable in any known manner to separate the plates at the joint whenv connected in the manner specified. Moreover, by means of this improved fastening the necessity of impairing the integrity of the plates for the insertion of bolts or con.- necting the plates by the use of threads is avoided.

' l The projections formed in the mannerherein shown and described constitute levers, the end sof which form fulcrums and to which levers the fastening devices are usually applied substantiallymidway of their length,

this means may be independent ofthe tiebolt, and in this instance each of the projections is shown provided in its'inner face with a recess or slot 15, which when in communication with a similarvrecess o r slot of a companion registering projection forms a keyway 16 for the reception of a key 17, by'lnea'ns of which the projections and the members or plates formed as a part thereof or rigid therewith may be located in proper alinement and in fixed position relative to each other, so that the forcing of one plate inwardly inde.- pendent of its companion plate is prevented. In some structures this same resultl may be accomplished by providing the projections with exteriorly-located transversely-extending recesses 20, (see Fig. 7,) into which the I-bolts shrink after they have been heated and located in proper position, so that the surfaces 2l in engagement with the faces 22 of such bolts prevent the forcing of one plate inwardlyindependent of its companion plates, such tie-bolts thus acting as keys.

In the form of fastening shown in Fig. 8 th tie-bolts, while of I-shaped formation, have their heads provided with inclined side faces 25, the projections 2 3 being formed with complementary inclined faces 26. Thus the bolts are in the nature of wedges and when shrunk into position on the wedge-shaped faces of the projections will act in a very eective manner to not only clamp but wedge the plates together.

By the provision of the present fastening means it will be seen that the necessity of forming the plates or components of material which it is practicable to drill or work by cutting or boring tools isl avoided, as the tiebolts are located on the exterior of the pro'- jections. Consequently the plates may be of such a tough character .that it is impracticable to drill, Work, or machine them other than by grinding operations. v

The term plate as used herein and in the claims is to be interpreted to include when the fastening is used to assemble the various parts of a vault or safe or analogous structure a front or other part of such structure,whether the sameis formed as an ordinary flat or curved plate or as a member formed of one or more parts.
